ATTORNEY Fatentecl Aug. 18, 1931 UNITED STATES LE ROY G. MORRIS, OF WATERLOO, IOWA REVERSIBLE CURRENT Application filed April 4,

My invention relates to improvements in air circulators, and the object of my improvement is to provide for motor cars or other inclosures, apparatus operative to circulate a 5 current of either. warm or unwarmed air therethrough.

Another object of my improvement is to render said apparatus reversible in action to permit the air current to be directed into different places in the inclosure primarily, and for the greater convenience and comfort of an occupant as desired.

Another object of my improvement is to supply valvular means in the apparatus which will be effective in practice to produce the last mentioned object, but will also be operable to shut oil the connection between said different places in the inclosure, while at the same time allowing an air current to be driven through the inclosure from one of said places or vents only in the creation of a regular and sustained air circulation through the inclosure and said apparatus.

Other objects will be described specifically hereinafter and defined in' the appended claims.

I have accomplished the said objects by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Fig. 1 is a diagrammatic view in side elevation of a motor car, with parts in longitudinal vertical section, removed or broken away, and showing my improved apparatus associated operatively therewith. Fig. 2 is an enlarged front elevation of the valve chamber with the rotary blower removed. Fig. 3 is a like viewof the valve chamber with its front wall removed. Fig. 4 is a top plan view of the valve chamber with the blower associated therewith, having a part ofthe chamber broken away, and Fig. 5 is a central vertical longitudinal section of the heater casing with other elements in elevation, and on another enlarged scale than said Figs. 2 to 4 inclusive. While my apparatus is shown as associated with a motor car for the creation of a constant air circulation throughout the interior of its body, yet in principle the apparatus may,

with necessary modifications in details, be

HEATING APPARATUS 1930. Serial No. 441,626.

adapted for an air circulation means for any inclosure, such as an apartment in a dwelling or other'structure.

The numeral 43 denotes the motor of a car, having the usual exhaust pipe 44 or manifold with the communicating vent tube 37 which is bent downwardlyand carried thence 1on gitudinally belowthe floor 33 of the car body to the rear. to a mufiler. Fig. 1 shows the body soseated as to have forward and rear spaced cross seats. In their interspaces and immediately to the rear of the dashboard in the front interspace and the front seat in the rear interspace of the seats, the floor has apertures covered by a guard grating or apertured cover 35 and 23 respectively of like shape, designed to open at the sides to either draw airthereinto from the floor level, or to vent air therealong,-as the case may be when the apparatus is difierently adjusted.

The numeral 41 denotes a hollow cylindrical casing, preferably as shownin Fig. 5, shaped froma metal sheet formedinto a cylinder and having its longitudinal edges crimped for union at 42, the casing being initially mounted in spaced relation concentrically about the exhaust pipe 37 below the floor 33 and intermediate the said floor apertures. The cylinder 41 has cup-shaped end caps 38 made up of mating halves with flanges 39 at the bottom secured removably together, and at the tops by screws or bolts to'the entrant end parts of the cylinder, the caps having central sleeves fitting upon the exhaust pipe. The caps have erect tubular seats 40 to receive the lower ends of flexible hose sections 36 and 34 at front and rear, the

. section 36 delivering to the apertured guard grating 35 in front of the front seat and prof erably to the right hand of the steering wheel, and the other section 34 being in communication with a sleeved port 9 in the lower part of avalve-chamberv 1 immediately below the floor aperture which is beneath the rear guard 1 member 23, said valvechamber having a pair of open top conduits 6 and 7 which enter the rearfloor aperture to be flush with the upper end thereof. Said casing is thus readily as seinbledor removed.

The valve chamber 1 as shown is rectangiis lar in shape, closed at the bottom by a plate 2, the lower space therein in communication with the sleeved port 9 serving as a by-pass 8 for compartments 4: and 5 thereabove defined medially by a vertical partition 11, the chamber being closed at the top between the conduits 6 and 7 by a removable top flanged closure plate 10.

The compartments 4 and 5 are always in direct communication with said top conduits 6 and 7. These compartments contain the flanged valves and 19 respectively, which have semicircular front flangere cesses 16 and 20 to register with the lower partscfthe'pair of front wall circular apertures 12 and 13 occasionally, and with the nozzles 29 and 30 respectively secured in communication with said apertures by the headless screws 31 mounted in threaded holes in the rear wall part of a fan-wheel chamber 25 having an operating electric motor 24', said screws entering thre'aded holes 1 1 in the front wall ofthevalve chamber. The motor has the usual pair of conductors 26 and 27 leading to the terminals of a battery or other source of electric current 28. Said valves have respective- 1y like erect fixed. central operating rods 17 and 21. terminating at their upper ends in finger buttons 18 and 22 respectively, and the valves may be pushed up or down independ- "ently manually and slidingly in the compartments 4 and; 5to controlv the communications between the b'yrpass 8 and the compartments and conduits 6 and 7, as also the communications of both with the fan-wheel chamber 25.

In cold. weather the exhaust pipe 37-being highlyheated, may warm the air in the casing 41? passingtherethrough in either of. opposite directions to enter the body of, the car by either the front conduit. 36 or between the "front and rear seats by the rear conduit 34:,

according to the adjustments relatively of. the valves 15 and 19 in the valve chamber 1'. The motor being started to rotate the fan in the housing 25, and the valvesset as 'in Fig.

- 3, air is drawn fromrbetwe en the seats and the grating 23 downwardly by way of. the conduit6, compartment 4;, front port 12, fanhousing 25, andpropelled through front port 13, bypass 8, conduit 34, casing 11 to be there heated, and thence delivered through the cons duit' 3.61 to the front grating 35. When the positions of-said valves are reversed, the air is'reversely directed to deliver'warined air into the rear grating 23, andiin both cases a.

' circulation'in the car is set up between said gratings. In warm weather, both valves may be pushed down together, thus shutting off the by-pass 8 and casingal, and thenthefanwheel drives air from one conduit. 6to the "other, creating a cool. aircirculation inthe carat the grating 23, butwhich is forced throughout the car, I Three adjustments are thus efiected for the convenience of the users.

Having described my invention, What" I claim as new, and desire to secure by Letters Patent, is:

1. In a device of the character described, a blower, a valve-chamber in communication with the inletand outlet-ports of the blower, said chamber having conduits leading into paced parts of an inclosure and containing valves intermediate said conduits movable to control the communications between said inletand outlet-ports with the conduits to permit reversal of an air current caused by said blower from one condut to the other, said valves when both moved in the same and one direction only operating to cut oif the communication of the valve-chamber with one conduit while permitting the blower to create a circulation of air througl' the chamber and said inclosure byway of'c-ertain conduits of said chamber only, which lead into one part of and both sets of conduits to reverse the direc} tion of an air current in said chamber between said sets, said valves being also movable together in one direction only to thus cut 01f the communication of-the chamber and blow.- er with the first-mentioned conduit, while permitting the blower to createani air circulation through said chamber andthrough said inclosure by way of said pair of conduits.

3. In a device of the character described, a valve-chamber having a pair of like compartments opening at one end thereof-into. an inclosure, the opposite end of the chamber being closed and containing a by-pass for occasional separate communications with the other ends of said compartments, independently operable valves mounted reciprocatingly in said compartments, said chamber having ports opening into said compartments, a blower having communication with said ports, said valves controlling the communications between said blower, said compartments and said by-pass, and a con duit in communication between said by-pas s and another part of said inclosure.
